Em um conjunto de cafeeiros existentes em Mundo Novo, hoje Urupês, na região Araraquarense do Estado de São Paulo, foram feitas seleções de vários cafeeiros baseando-se no seu aspecto vegetativo, na produção existente na época da seleção e na provável produção do ano seguinte. Estudou-se a origem da plantação inicial desse café, tanto em Urupês como em Jaú, chegando-se à conclusão de que é provavelmente originário desta última localidade. Progênies do café "Mundo Novo", anteriormente conhecido por " ...

Nephrolithiasis has rarely been reported in marine mammals. During 2004 and 2005, two cases of nephrolithiasis were diagnosed during routine necropsy examination, one in a northern elephant seal (Mirounga angustirostris) and one in a California sea lion (Zalophus californianus). Nephroliths were found throughout both kidneys during necropsy examination, varying in size from 1–10 mm in diameter in the northern elephant seal and from 1–15 mm in diameter in the California sea lion. Necropsy and histopathology ...

Abstract Background Splenic nodules and heterogeneous parenchyma are seen frequently in abdominal ultrasound examinations of dogs, but the clinical importance of these lesions remains unclear. Objectives To determine whether specific ultrasonographic findings correlate with clinically relevant cytologic diagnoses and determine what sonographic features are correlated with these diagnoses. Another objective was to develop a scoring rubric to help clinicians make decisions on whether or not certain ...

Recent studies have been conducted in Brazil using molecular techniques for the detection of hemotrophic mycoplasmas in several mammals. In domestic cats, Mycoplasma haemofelis, "Candidatus M. haemominutum", and "Candidatus M. turicensis" infections have been identified. These species have also been found in free-ranging and captive neotropical felid species. Two canine hemoplasmas, Mycoplasma haemocanis and "Candidatus Mycoplasma haematoparvum", have been identified in dogs. In commercial swine populations, ...

Animal population estimates are essential for public health services to ensure the success of zoonoses control programmes. Canine and feline populations vary among different regions mainly because of local human income status and type of human residence. Accordingly, the present study estimated the pet population size living in apartments of a vertical neighbourhood in Curitiba, Brazil. We chose a neighbourhood with a predominance of apartment buildings. All apartment buildings were visited, and ...

Abstract Hemotrophic mycoplasmas infect a variety of mammals. Although infection in humans is rarely reported, an association with an immunocompromised state has been suggested. We report a case of a Mycoplasma haemofelis–like infection in an HIV-positive patient co-infected with Bartonella henselae.

The two most common haemotropic Mycoplasma of cats, Mycoplasma haemofelis and 'Candidatus Mycoplasma haemominutum' have been identified using molecular techniques in all continents, except Antarctica. We report the first molecular characterization in South America of a dual infection with M haemofelis and 'Candidatus Mycoplasma haemominutum' in three domestic cats. The 16S ribosomal RNA gene was amplified in three anaemic cats in which haemoplasma organisms were seen attached to the erythrocytes in ...

Ehrlichiosis is a disease caused by rickettsial organisms belonging to the genus Ehrlichia. In Brazil, molecular and serological studies have evaluated the occurrence of Ehrlichia species in dogs, cats, wild animals and humans. Ehrlichia canis is the main species found in dogs in Brazil, although E. ewingii infection has been recently suspected in five dogs. Ehrlichia chaffeensis DNA has been detected and characterized in mash deer, whereas E. muris and E. ruminantium have not yet been identified ...

Hypokalemia is more common than hyperkalemia and usually is caused by excessive losses of potassium from the kidneys or gastrointestinal tract. Serum potassium should be investigated in patients developing chronic or frequent vomiting or diarrhea, marked polyuria, muscle weakness, or unexpected cardiac arrhythmias, as well as in those undergoing therapy with insulin, diuretics, or total parenteral nutrition. Clinical signs develop when serum potassium deficit is moderate or severe.

Severe respiratory syndrome coronavirus 2 (SARS-CoV-2), responsible for the Coronavirus disease 2019 (COVID-19), is the causative infectious agent of the current pandemic. As researchers and health professionals are still learning the capabilities of this virus, public health concerns arise regarding the zoonotic potential of SARS-CoV-2. With millions of people detected with SARS-CoV-2 worldwide, reports of companion animals possibly infected with the virus started to emerge. Therefore, our aim is ...

Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2)-positive pet owners are reported to be a risk factor for infection of their pets; however, the influence of the viral load and associated risks has not been fully established. This study aimed to assess potential association of viral load in owners with the presence of SARS-CoV-2 infection in their dogs. Of 20 SARS-CoV-2-positive pet owners from 13 families in Curitiba, Brazil, 5 of 22 (22.7%) dogs were positive for SARS-CoV-2. Viral presence ...

Chloride is an essential element, playing important roles in digestion, muscular activity, regulation of body fluids, and acid-base balance. As the most abundant anion in extracellular fluid, chloride plays a major role in maintaining electroneutrality. Chloride is intrinsically linked to sodium in maintaining osmolality and fluid balance and has an inverse relationship with bicarbonate in maintaining acid-base balance. It is likely because of these close ties that chloride does not get the individual ...

The mechanisms for compensation as well as the values obtained from several studies using normal dogs and dogs with experimentally induced diseases are provided. Compensation is not the same in dogs and human beings. Dogs have a better ability to adapt to most respiratory disorders, and human beings adapt better to metabolic acidosis. In metabolic alkalosis and chronic respiratory acidosis there is no difference ...

Summary The Physiology of chioride ion and its relationship to clinical disorders in small animall practice is reviewed. Chioride is the major anion in the extracellular fluid and is important in the metabolic regulation of acid‐base balance. A new clinical approach is used to assess chloride ion changes after accounting for changes in free water. Using this approach chloride disorders can be divided into corrected and artifactual. Changes in free water are solely responsible for the chioride ion ...

Atrial natriuretic peptide (ANP) and brain natriuretic peptide (BNP) are cardiac hormones involved in electrolyte and fluid homeostasis. Our laboratory has investigated the use of ANP and BNP as diagnostic markers of cardiac disease in cats. We hypothesize that the cardiac distribution of ANP and BNP increases in cats with hypertrophic cardiomyopathy (HCM). Accordingly, we evaluated the immunohistochemical distribution of ANP and BNP in hearts of four cats with naturally occurring HCM relative to five ...

Babesia gibsoni was first recognized in India in 1910. Analysis of 18S rRNA has shown that there are at least three distinct isolates that are morphologically identical. Although organisms similar to B. gibsoni have been identified in peripheral blood smears from one dog in Brazil, this isolate has not been molecularly characterized. Accordingly, we obtained blood samples from 16 dogs with intraerythrocytic inclusion bodies. DNA was extracted and amplified with primers that detect a segment of the ...
